The first equilibrium notion that we provide – called myopic team-wise stability – is a direct generalization of the concept of pair-wise stability, from [1]}, which is used in network formation games , such as [2]}. The original notion only considers activities performed in pairs while the present extension allows for activities performed by groups of different sizes.More precisely, in the model by [2]} Assumption REF  always holds and, in the language of [4]}, agents' capacity of forming links and performing tasks is assumed unbounded.
